another piece of weirdness

There are similar examples here  in painshill's response.

Look at the link here, again. Banded chert photos at the bottom of page are enlightening.

I see them before my post, but I'm still wondering about a weathered secondary overgrowth on chert nodule.

The exterior of this piece looks to be chert cortex, do you agree?

 

I've been trying to figure out the weathering of layers on the fat end and how they're arranged.  It's rather complicated but possible.

I don't exclude that possibility. This picture shows that the foldings have a curvilinear pattern on surface at the narrowing end, resembling a secondary overgrowth, not saying that the fat end hasn't a quite resemblance with the sketch of Seilaher's example,   although the surface is weathered. It's definitely chert, or similar, as it was supposed. It has nothing to do with bivalves / oysters, but is a nice example of what Mother Nature may produce, putting us in uncertainty.

And that's the continuous beauty of it.

Can You follow the ridges all the way around the object to see if they are in a spiral or concentric rings?

 

I still do not see more than a vague resemblance to a spiral coprolite, but wait for the tagged members to give their opinions.

Very cool piece! Are the rings concentric or spiral?

That is what I would like to know.

 

@hndmarshall could You please let Us know.

its kind of like wrapped like one would with tape...except where the pattern is.....this item reminds me of a carved scarab...I may wire wrap it and make me a necklace out of it...that way I can wear it!..good conversation piece. 

 

if you look at the back part you can see the wrapping better and at the fattest part where it looks like the wrapping has folded over on itself.

I'm still not clear on this (sorry). Like a single piece of tape wound around something slightly offset with each round (spiral) or separate pieces of tape wound once (concentric)? The reason I ask is banded chert and concretions would have concentric rings. Coprolites generally do not. If this was not found in Texas, I would immediately write it off as geologic. That said, I have seen some very odd spiral/scroll coprolites from the Eagle Ford Group and Ozan. Yours kind of reminds me a bit of this type from the Eagle Ford.
